Lower back pain primarily affects the lumbar vertebrae. Medical experts classify it into three main types: acute, subacute, and chronic. Acute pain lasts less than one month and is often a sudden lumbago episode—intensely sharp and debilitating. Subacute pain persists between one and three months, fluctuating between intense episodes and periods of relief. Chronic pain develops gradually and endures beyond three months.
Don't ignore back pain—its characteristics can signal serious issues. Pain radiating down the leg that worsens with coughing or straining often indicates sciatica. Sudden onset after physical exertion or awkward movement may point to muscle strain, ligament sprain, or disc displacement. Morning stiffness could signal osteoarthritis, while sharp nighttime pain might stem from inflammation or even a tumor.
Acute lower back pain often results from back strains during sports, heavy lifting, or intense effort. Chronic pain frequently arises from repeated movements, poor posture, or minor injuries to muscles, tendons, or ligaments. Herniated or slipped discs, triggered by incorrect positioning, excess weight, or pregnancy, are common culprits. Inflammatory conditions like osteoarthritis or arthritis, bone disorders such as osteoporosis or spondylodiscitis, and kidney issues including renal colic or pyelonephritis can also provoke persistent pain.
